Abstract
In systems and methods of varying a latency timer in a wireless communication system, a network identifier associated with an access node in communication with a wireless device is received at a communication node during the establishment of a communication session between a wireless device and the communication node. At least one latency timer criteria is determined based on the network identifier, and at least one latency timer is adjusted according to the latency timer criteria.
Claims15
A method of varying a latency timer in a wireless communication system, comprising:
- receiving at a communication node from a first wireless device a first network identifier associated with an access node in communication with the first wireless device during the establishment of a communication session between the first wireless device and the communication node, wherein the access node is associated with a first communication network, and wherein the first network identifier indicates a network latency of the first communication network;
- determining at least one registration latency timer criteria based on the first network identifier;
- adjusting at least one registration latency timer according to the determined at least one registration latency timer criteria to complete a registration of the first wireless device with the wireless communication system;
- receiving at the communication node a call request comprising a second network identifier from a second wireless device in communication with a second access node associated with a second communication network;
- determining at least one call latency timer criteria based on the second network identifier;
- and
- adjusting at least one call latency timer according to the determined at least one call latency timer criteria to complete a call setup between the wireless device and the second wireless device.

A system for varying a latency timer in a wireless communication system, comprising:
- an access node in communication with a first wireless device, wherein the access node is associated with a first communication network;
- and
- a communication node in communication with the first wireless device through the access node configured to
- receive a first network identifier associated with the access node during the establishment of a communication session between the first wireless device and the communication node, wherein the network identifier indicates a network latency of the wireless communication system, to determine at least one registration latency timer criteria based on the network identifier, and to adjust at least one registration latency timer in at least one of the communication server and the first wireless device according to the determined at least one registration latency timer criteria to complete a registration of the first wireless device with the wireless communication system, and
- receive a call request comprising a second network identifier from a second wireless device in communication with a second access node associated with a second communication network, determine at least one call latency timer criteria based on the second network identifier, and adjust at least one call latency timer according to the determined at least one call latency timer criteria to complete a call setup between the first wireless device and the second wireless device.
